Hi there,
what if you were to find a war veteran from those years and ask a few of them. They might even have a few medals for you to look at.
Or ask your friends and relatives if they have an older uncle or family member who was a soldier and who lives in your same town. They would be glad to show you their medals.
Last year some of the students in my son's class brought their grandfather's and grandmother's ( yes, women, too were active in the war) to school for their Rememberance Day assembly. They brought in a jacket/ hat and medals to show the students.
Another place would be to go look for ideas.... maybe the museum..... or I hate to say that I have seen medals in the pawn shops;(......
Oh, maybe check the internet.... but real ones give you a better idea!:0
Hope that helps .
